 Log Message:
 PR kern/41923: assertion "cur != owner" failed
 In the for(;;) loop of turnstile_block(), the lock owner can change while
 cur's lock is released (cur's lock is also the tschain_t's mutex).
 Remove the KASSERT about owner being invariant and try to deal with the
 fact that the owner can change instead.
